And this is what happens when you mix too much resin at once and don't keep it cool!! Opps!! Live and learn!

The entire underside of the floor was soft due to the PO not venting the area after use and during the winter. So the wood that is just glued to the underside rotted out. I left about a 4 inch border all around and cut the floor out, (4" mini grinder is your best friend) then scraped and sanded the underside of the floor bare, then glued new irregular shaped marine plywood pieces to the underside, then fiberglassed everything with a thin coat of woven glass to seal the wood against further rotting. (The reason for the irregular shaped pieces (think of a jigsaw puzzle) is that it's stronger than large squares or rectangles since there are no transverse running joints). Once that was done I discovered that all the foam flotation was waterlogged, so removed that, cleaned out everything, ran new hoses for the gas tank (since it was open it just seemed like the logical thing to do) and re-foamed the voids. But instead of foaming just to the void lips, I foamed all the way to the underside of the deck, so the deck actually rests on a bed of foam. (nice and solid as a rock) To attach the deck back on, I glued and screwed strips of plywood to the underside of that previously mentioned 4" border, leaving them about 2 inches proud , then spread glue on the shelf that created, laid the deck onto it and screwed it down. Filled the cracks with thickened resin, sanded everything, masked it all off and applied the U-Pol, tinted to a very light shade of tan, almost white. No, it doesn't get any hotter than a regular painted deck, and the rubbery feeling on the feet is actually soothing, with great anti-slip properties.
One of the really nice things about the truck bed liner material is that it's so thick that it completely hides all cracks and screwheads, giving the finished project a seamless look to it. The only bad thing about the stuff is that it's going to be a bear if I ever have to remove it. The last thing I did was cut out the floor and installed that hatch you see in the second picture between the captains chair and the mates chair area. There's a huge void there that Wellcraft never did anything with, and it makes a perfect storage area. ( I may move my batteries up there come springtime, but that's just a dream for right now.

Too bad you decided to take so many short cuts ha Just kidding ... wow I guess that's what they call going the whole 9 yards. PO= Previous owner?? How did you apply the foam? That's a bit beyond the spray cans at the hardware store it would seem? So... when you did the foam did you let it rise above the floor line then cut it off flat at the correct height? I used foam to repair a kitchen floor that was 2x4's laid flat over concrete then 3/4 ply. They didn't secure them to the concrete at all I don't think. So over the years the 2by's warped a bit and so there was a spongy feel to the floor. I drilled about 40 1/4" holes and spayed about 10 cans of expanding foam under the floor. It worked fantastic. The floor is solid! Always more than one way to skin a cat.

I can certainly see your point about that bed liner being nice and thick to hide the cut edges and screw heads. That alone probably negated any need to resin the entire floor. How long has it been on there? Guess it lasts okay? No indication of peeling on the edged? You know how rubber glue tend to roll loose at the edges. You say you tinted it that color so I assume it came in white?

You make me wonder if I could cut an access door for storage just ahead of the center console on my V20. Any idea if there is a empty void there? I would definitely need a completly waterproof cover. But worth the effort if it's doable you can never have too much storage.

Just wondering if this would make a nice storage spot. Is it void do you know?

Sorry, I know nothing about the underside of center consoles.... it would seem to be about right. But if you want I can measure from the inside of the transom to the hatch. That should be about the same... bu8t like I ssiad, I really do not know.

Yes, the base coat comes in either white or black, and tinting runs the color spectrum.
No, there is no peeling on the edges This stuff sticks like a tongue to a metal pipe in winter.
The foam is a two part that comes in plastic bags inside of cardboard boxes. You mix and then have about 5 minutes to pour before it starts it's expansion. I foamed to the top, then trimmed it flat, which involved several trial fits of the deck on top of it.
The U-Pol has been on for 2 years now with no signs of any wear or deterioration.
`

a trick for that is to pour the foam then temporarily screw down (weigh down) a piece of plywood with some 1"-2" holes in it (to allow expansion), then remove ply leaving foam flush with stringers

Gotta admit I never thought about that. I guess you can teach an old dog new tricks after all. Thanks Skunk. (Hopefully I'll never have to do that job again and use that trick though) :beer:.
